The average elevation of this region is about , but it rises as high as where it meets the western edge of the eastern highlands. The eastern highlands region is the highest and most rugged portion of the country. It extends for more than from above Lake Albert to the country's southern tip and varies in width from . Its hills and mountains range in altitude from about to more than . The western arm of the Great Rift Valley forms a natural eastern boundary to this region. The eastern border of the DRC extends through the valley and its system of lakes, which are separated from each other by plains situated between high mountain ranges. In this region, changes in elevation bring marked changes in vegetation, which ranges from montane savanna to heavy montane forest. The Rwenzori Mountains between lakes Albert and Edward constitutes the highest range in Africa. The height and location of these mountains on the equator make for a varied and spectacular flora.

Its flow is unusually regular because it is fed by rivers and streams from both sides of the equator; the complementary alternation of rainy and dry seasons on each side of the equator guarantees a regular supply of water for the main channel. At points where navigation is blocked by rapids and waterfalls, the sudden descent of the river creates a hydroelectric potential greater than that found in any other river system on earth. Most of the DRC is served by the Congo River system, a fact that has facilitated both trade and outside penetration. Its network of waterways is dense and evenly distributed through the country, with three exceptions: northeastern

ial forest, where daytime highs range between , and nighttime lows rarely go below . The average annual temperature is about . In the southern uplands, particularly in the far southeast Katanga region, winters are cool and dry, whereas summers are warm and damp. The area embracing the chain of lakes from Lake Albert to Lake Tanganyika in the eastern highlands has a moist climate and a narrow but not excessively warm temperature range. The mountain sections are cooler, but humidity increases with altitude until the saturation point is reached; a nearly constant falling mist prevails on some slopes, particularly in the Rwenzori Mountains. The seasonal pattern of rainfall is affected by the DRC's straddling of the equator. In the third of the country that lies north of the equator, the dry season (roughly early November to late March) corresponds to the rainy season in the southern two-thirds. There is a great deal of variation, however, and a number of places on either side of the equator have two wet and two dry seasons. Rainfall averages range from about . Annual rainfall is highest in the heart of the Congo River basin and in the highlands west of Bukavu and with some variation tends to diminish in direct relation to distance from these areas.
